You really are a riot!
You may be right about those that use abortion as birth control, but if they have aborted, and are still alive, they can still repent. If a woman aborts a child for a medical reason, while sad, it isn't a sin. They aren't aborting for birth control. They aren't doing it maliciously and intent matters in this. They are doing it because the fetus was going to die anyway. They aren't doing it because they don't want to be pregnant. They are doing it because the fetus/pregnancy is killing them. If the fetus/pregnancy is killing them too, why should two die when the mother can live by having an abortion?
You do realize that if she chose not to abort, and the fetus/pregnancy is killing her that the fetus will die anyway?
Jesus will be merciful to them.
